I've been trying to make ginger beer and the first attempt bombed, for some reason. I'm not clear if it's because of residual bleach, or tap water at the wrong point, or what. I was about to give up and toss the ginger bug out when I saw it was relentlessly fizzing so I gave it another shot.
I bottled the 4L of mixture (with 200ml of Ginger Bug) into flip-top bottles. Twenty four hours later I wanted to check the carbonation, so I opened the first bottle. It blew the cap right off and dumped about half the bottle's contents on the floor. The other three bottles were pretty much the same, although I managed to open them more carefully.
My question is - what can I do to avoid this in the future? This is the first thing I've "brewed" - is there some equipment specifically to address this problem? Some jug with a pressure valve?
Does releasing the built up pressure in a bottle harm the carbonation of the beer? I know opening a bottle of coke will make it go flat, eventually. How is it different for ginger beer?
